- Description: Background: As basketball match-play requires players to possess a wide range of physical characteristics, many tests have been introduced in the literature to identify talent and quantify fitness in various samples of players. However, a synthesis of the literature to identify the most frequently used tests, outcome variables, and normative values for basketball-related physical characteristics in adult male basketball players is yet to be conducted. Objective: The primary objectives of this systematic review are to (1) identify tests and outcome variables used to assess physical characteristics in adult male basketball players across all competition levels, (2) report a summary of anthropometric, muscular power, linear speed, change-of-direction speed, agility, strength, anaerobic capacity, and aerobic capacity in adult male basketball players based on playing position and competition level, and (3) introduce a framework outlining recommended testing approaches to quantify physical characteristics in adult male basketball players. Methods: A systematic review of MEDLINE, PubMed, SPORTDiscus, Scopus, and Web of Science was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify relevant studies. To be eligible for inclusion, studies were required to: (1) be original research articles; (2) be published in a peer-reviewed journal; (3) have full-text versions available in the English language; and (4) include the primary aim of reporting tests used and/or the physical characteristics of adult (i.e., ≥ 18 years of age) male basketball players. Additionally, data from the top 10 draft picks who participated in the National Basketball Association combined from 2011–12 to 2020–21 were extracted from the official league website to highlight the physical characteristics of elite 19- to 24-year-old basketball players. Results: A total of 1684 studies were identified, with 375 being duplicates. Consequently, the titles and abstracts of 1309 studies were screened and 231 studies were eligible for full-text review. The reference list of each study was searched, with a further 59 studies identified as eligible for review. After full-text screening, 137 studies identified tests, while 114 studies reported physical characteristics in adult male basketball players. Conclusions: Physical characteristics reported indicate a wide range of abilities are present across playing competitions. The tests and outcome variables reported in the literature highlight the multitude of tests currently being used. Because there are no accepted international standards for physical assessment of basketball players, establishing normative data is challenging. Therefore, future testing should involve repeatable protocols that are standardised and provide outcomes that can be monitored across time. Recommendations for testing batteries in adult male basketball players are provided so improved interpretation of data can occur.

- Description: With the prevalence of customized self-report measures in high-performance sport, and the incomplete understanding of athletes' perceived wellness in response to matches and training load, the objective of this study was to explore weekly wellness profiles within the context of the competitive season of professional Australian football. Internal match load, measured through the session-rating of perceived exertion method, match-to-match microcycle, stage of the season, and training load were included in multivariate linear models to determine their effect on weekly wellness profile (n = 1,835). There was a lower weekly training load on a 6-day microcycle compared with a 7-day and 8-day microcycle. Match load had no significant impact on weekly wellness profile, while there was an interaction between microcycle and days postmatch. There was a likely moderately lower wellness Z-score 1 day postmatch for an 8-day microcycle (mean; 95% confidence interval: -1.79; -2.02 to -1.56) compared with a 6-day (-1.19; -1.30 to -1.08) and 7-day (-1.22; -1.34 to -1.09) cycle (d; 95% confidence interval: -0.82; -1.3 to -0.36, -0.78; -1.3 to -0.28, respectively). The second half of the season saw a possibly small reduction in overall wellness Z-score than the first half of the season (0.22; 0.12-0.32). Finally, training load had no effect on wellness Z-score when controlled for days postmatch, microcycle, and stage of the season. These results provide information on the status of players in response to matches and fixed conditions. Knowing when wellness Z-score returns to baseline relative to the length of the microcycle may lead practitioners to prescribe the heaviest load of the week accordingly. Furthermore, wellness "red flags" should be made relative to the microcycles and stage of the season to determine an athlete's status relative to their typical weekly profile. © 2016 National Strength and Conditioning Association.

- Description: Effective sport talent identification and development (TID) programmes are integral to a nation's success in international sport. Using a transdisciplinary approach that involved sport practitioners and researchers with diverse theoretical perspectives, we investigated TID factors in four Australian sports (Australian rules football, cricket, kayaking and tennis). A transdisciplinary approach allowed us to isolate and explore a range of factors critical to successful sport TID. This methodological article explores how this project moved TID research beyond its paradigmatic, quantitative, sport science lens and advanced knowledge and practice in TID from both theoretical and applied perspectives. The use of a transdisciplinary approach in future TID research is recommended.

- Description: The current investigation aimed to understand the positional profile of repeated high-intensity-effort activity (RHIE) across halves during elite rugby union match-play. Forty elite rugby union players ( n = 40) were monitored across match-play during a single season. Player’s locomotor profiles were recorded using wearable microtechnology (GPS Catapult S5, Australia). Locomotor activity was classified across total distance (m) running distance (m ≥ 4.4 m s −1 ) high-speed running (≥ 5.5 m s −1 ) sprint distance (≥ 7 m s −1 ) accelerations (≥ 2 m s −2 ) decelerations (≤ − 2 m s −2 ) and collisions (≥ 4 g). Peak velocity (m s −1 ) total efforts ( n ) high-intensity efforts (HIE), repeated high-intensity efforts (RHIE), total number of RHIE bouts ( n ), maximal number of efforts within a RHIE bout ( n ) and recovery times between RHIE (s) were also recorded across match-play. Players were shown to complete 164 ± 30 HIE per game. Overall players performed 11 ± 6 RHIE bouts. The mean efforts per RHIE bout was 4 ± 1 with a maximum of 6 ± 2. RHIE positional differences were reported with back-rows completing the most total efforts when compared to all positions within the forwards (ES: 1.33–5.29 moderate–very large ). Significant reductions were reported between halves for all running and repeated effort variables. The data highlight the potential consideration that RHIE should be given by coaches when preparing players for rugby union match-play. An understanding of the positional differences in RHIE can assist coaches in designing training drills that can expose players to these match-play requirements.

- Description: The purpose of this research was to determine 1) the relationship between lower-body strength qualities and baserunning and 2) the relationship between lower-body strength qualities and the time discrepancy between baserunning and linear sprints of the same distance. Twenty-one male baseball players (age: 17 ± 1.11 years; height: 179.5 ± 6.73 cm; body mass: 82.48 ± 11.1 kg) from a State Baseball Academy were tested for peak force (PF) production in an isometric mid-thigh pull (IMTP), peak power (PP) and jump height (HCMJ) in a countermovement jump (CMJ), and reactive strength index (RSI) from a drop jump (DJ). Additionally, they performed sprints from Homeplate to Second Base (54.8mBR) and over a 54.8m linear distance (54.8mLIN), with splits taken at 10m (10mBR, 10mLIN) and 27.4m (27.4mBR, 27.4mLIN). Relationships between all the collected variables plus the difference between 54.8mBR and 54.8mLIN (BRD), relative PF (RelPF) and relative PP (RelPP) were assessed by Pearson product-moment correlation coefficient.

- Description: Background: Previous research suggests that children with or at risk of probable developmental coordination disorder (pDCD) activate different areas of the brain when performing certain motor skills compared with typically developing (TD) children. This study used functional near-infrared spectroscopy to compare prefrontal cortex (PFC) activity in TD and pDCD during the completion of manual (three-dimensional [3D]) and computerized versions (two-dimensional) of the Tower of Hanoi (ToH) puzzle. Method: A total of 12 children (TD and pDCD; one female/11 male, -x = 10.36, SD ± 1.52 years) performed the two-dimensional and 3D conditions of the ToH disk tasks, with equivalent executive function but different motor requirements, with functional near-infrared spectroscopy to compare PFC activity. Results: Interestingly, brain oxygenation levels were more apparent in the 3D versus two-dimensional ToH. In the 3D, there were large differences between pairs of discordant sibling sets and this was located to the right medial PFC, with pDCD exhibiting less activation in this region. Conclusion: While only exploratory, we have identified potential differences in the right medial PFC region, which differs within sibling sets with different pDCD status. These results concur with previous studies and are an area that needs to be explored further with a larger cohort of TD and pDCD. © 2023 Human Kinetics Publishers Inc.. All rights reserved.

- Description: Objectives: This study aimed to determine whether elite cricket umpires' decisions contribute to home advantage via leg-before-wicket decisions. Design: Leg-before-wicket decisions (n = 4971) from actual elite level cricket matches in Australia between 2009 and 2016 were analysed using a binomial logistic regression to predict the umpires' leg-before-wicket decisions. Methods: Regressions were performed to determine whether the batter's team (home or away) influenced the likelihood that the umpire would give them out leg-before-wicket. Results: We found no evidence of home advantage in umpires' leg-before-wicket decisions. In fact, we found evidence that umpires in some instances disadvantage the home team. Conclusions: We suggest that the increased professionalism of sports officials, and the scrutiny they are placed under, may lead umpires to reduce or even overcompensate for any existing biases in their decision making. © 2022 Sports Medicine Australia

- Description: The drop off in physical activity (PA) for children has led to an increased focus on their PA engagement, due to the poor health outcomes often linked to this decline. Subsequently, stakeholders, across a variety of fields, have problematised and intervened in activity settings to address this decline. Many of these studies acknowledge high levels of activity in the primary years and tend to prioritise their efforts on the adolescent years. An important limitation in these studies is that they greatly overlook how a decline might also be related to children’s physical engagement in early childhood. To gain more insight on the role that early PA engagement may play in long-term PA participation, this paper examines early physical engagement through a focus on year one/ two students across three PA spaces–the home, the physical education (PE) class and the playground. Data was collected through a range of ethnographic and child-centred methods and examined using a Bourdieusian lens. This analysis shows that engagement in PA starts as a confluence between the physically active habitus, sport-focused PE and the sportised playground, which produces different patterns of engagement. This paper offers an in-depth examination of this process across the three spaces and identifies how these outcomes become habitualised over the course of primary school, which may play a role in affecting long-term participation. The paper concludes with a call for a more democratised approach to early primary PE, along with accompanying changes to the playground. © 2022 Informa UK Limited, trading as Taylor & Francis Group.

- Description: Objective: To determine whether high or low adiposity is associated with youth sport-related injury.Data Sources: Ten electronic databases were searched to identify prospective studies examining the association between adiposity [body mass index (BMI) or body fat] and a future time-loss or medical attention sport-related musculoskeletal injury or concussion in youth aged 20 years and younger. Two independent raters assessed the quality (Downs and Black criteria) and risk of bias (Joanna Briggs Institute Critical Appraisal Tool). Random-effects meta-analyses were used to calculate pooled odds ratio [95% confidence interval (CI)] of injury.Main Results: Of 11 424 potentially relevant records, 38 articles were included with 17 eligible for meta-analyses. In qualitative synthesis, no clear association was identified between adiposity and any sport injury; however, 16/22 studies identified high adiposity as a significant risk factor for lower-extremity injury. Meta-analyses revealed higher BMI in youth with any sport-related injury and lower BMI in youth who developed a bone stress injury (BSI) compared with noninjured controls. The pooled OR (95% CI) examining the association of BMI and injury risk (excluding bone injury) was 1.18 (95% CI: 1.03-1.34). A major source of bias in included articles was inconsistent adjustment for age, sex, and physical activity participation.Conclusions: Level 2b evidence suggests that high BMI is associated with greater risk of youth sport injury, particularly lower-extremity injury and excluding BSI or fracture. Although pooled mean differences were low, anthropometric risk of injury seems to be dependent on type and site of injury in youth sport. © 2021 Wolters Kluwer Health, Inc.

- Description: Background: Previous studies have examined the relationship between external training load and creatine kinase (CK) response after soccer matches in adults. This study aimed to build training- and match-specific CK prediction models for elite youth national team soccer players. Hypothesis: Training and match load will have different effects on the CK response of elite youth soccer players, and there will be position-specific differences in the most influential external and internal load parameters on the CK response. Study Design: Prospective cohort study. Level of Evidence: Level 4. Methods: Forty-one U16-U17 youth national team soccer players were measured over an 18-month period. Training and match load were monitored with global positioning system devices. Individual CK values were measured from whole blood every morning in training camps. The dataset consisted of 1563 data points. Clustered prediction models were used to examine the relationship between external/internal load and consecutive CK changes. Clusters were built based on the playing position and activity type. The performance of the linear regression models was described by the R2 and the root-mean-square error (RMSE, U/L for CK values). Results: The prediction models fitted similarly during games and training sessions (R2 = 0.38-0.88 vs 0.6-0.77), but there were large differences based on playing positions. In contrast, the accuracy of the models was better during training sessions (RMSE = 81-135 vs 79-209 U/L). Position-specific differences were also found in the external and internal load parameters, which best explained the CK changes. Conclusion: The relationship between external/internal load parameters and CK changes are position specific and might depend on the type of session (training or match). Morning CK values also contributed to the next day’s CK values. Clinical Relevance: The relationship between position-specific external/internal load and CK changes can be used to individualize postmatch recovery strategies and weekly training periodization with a view to optimize match performance. © 2021 The Author(s).

- Description: Objectives: The aim of this study was to investigate potential moderators (i.e. lower body strength, repeated-sprint ability [RSA] and maximal velocity) of injury risk within a team-sport cohort. Design: Observational cohort study. Methods: Forty male amateur hurling players (age: 26.2 ± 4.4 year, height: 184.2 ± 7.1 cm, mass: 82.6 ± 4.7 kg) were recruited. During a two-year period, workload (session RPE × duration), injury and physical qualities were assessed. Specific physical qualities assessed were a three-repetition maximum Trapbar deadlift, 6 × 35-m repeated-sprint (RSA) and 5-, 10- and 20-m sprint time. All derived workload and physical quality measures were modelled against injury data using regression analysis. Odds ratios (OR) were reported against a reference group. Results: Moderate weekly loads between ≥1400 AU and ≤1900 AU were protective against injury during both the pre-season (OR: 0.44, 95% CI: 0.18–0.66) and in-season periods (OR: 0.59, 95% CI: 0.37–0.82) compared to a low load reference group (≤1200 AU). When strength was considered as a moderator of injury risk, stronger athletes were better able to tolerate the given workload at a reduced risk. Stronger athletes were also better able to tolerate larger week-to-week changes (>550–1000 AU) in workload than weaker athletes (OR = 2.54–4.52). Athletes who were slower over 5-m (OR: 3.11, 95% CI: 2.33–3.87), 10-m (OR: 3.45, 95% CI: 2.11–4.13) and 20-m (OR: 3.12, 95% CI: 2.11–4.13) were at increased risk of injury compared to faster athletes. When repeated-sprint total time (RSAt) was considered as a moderator of injury risk at a given workload (≥1750 AU), athletes with better RSAt were at reduced risk compared to those with poor RSAt (OR: 5.55, 95%: 3.98–7.94). Conclusions: These findings demonstrate that well-developed lower-body strength, RSA and speed are associated with better tolerance to higher workloads and reduced risk of injury in team-sport athletes. © 2018 Sports Medicine Australia

Dyads' experiences of taking part in Tai Chi classes for 20 weeks within the TACIT Trial were explored through class observations (n = 22 dyads), home-interviews (n = 15 dyads), and feedback. Data were inductively coded following thematic analysis. Tai Chi classes designed for people with dementia and their informal carers were enjoyable and its movements, easy to learn. Facilitators of participants' adherence were the socializing component and their enjoyment of the classes, whereas unexpected health problems were the main barrier. Finding the optimal level of challenge in the class setting might be crucial for people with dementia to feel satisfied with their progression over sessions and enable their continued participation. © 2021 Human Kinetics, Inc.

- Description: Objectives: To explore Australian cricket participants' knowledge of concussion assessment and management, and awareness of current concussion guidelines. Design: Cross-sectional survey. Methods: Novel and validated surveys were disseminated online, among over 16 year Australian cricket players and officials at the end of the 2018/19 cricket season. Data were collected on knowledge and awareness of concussion and analysed using descriptive statistics and crosstabulations. Further comparisons were made for the players between injured and non-injured, and helmet wearers and non-helmet wearers using Fisher's exact statistical test. Results: Both players (n = 224, 93 %) and officials (n = 36, 100 %) demonstrated strong knowledge of the importance of immediately evaluating suspected concussions. In comparison with players without helmets (n = 11), those using helmets (n = 135) considered replacing their helmets after a concussion to be vital to concussion assessment (p = 0.02). Overall, 80–97 % of players and 81–97 % of officials understood the importance of many factors regarding concussion management. When concussion management knowledge was compared by injury status, injured players (n = 17, 94 %) believed someone with a concussion should be hospitalised immediately, in contrast to non-injured players (n = 154, 69 %) (p = 0.04). Players (63 %) were less aware of concussion guidelines than officials (81 %). Conclusions: Overall, the knowledge of concussion assessment and management was satisfactory. However, there were discrepancies among players on some aspects of awareness of concussion guidelines. Increasing players' familiarity and experience in using the concussion guidelines is warranted. Targeted campaigns are needed to further improve concussion recognition and treatment at community-level cricket, so all participants play a role in making cricket a safe sport. © 2023

- Description: Background/Purpose of the study. Hamstring injuries are the most prevalent muscle injuries in both amateur and professional soccer (football) players. Eccentric strength deficits and muscle strength imbalances have been associated with an increased risk of muscle injuries. The current study is a non-randomised observational study investigating whether fatigue significantly reduces peak eccentric strength of the hamstring muscle group. Methods. Twenty-two right leg dominant professional football players participated in this study. None were injured or were rehabilitating from an injury at the time of testing. The eccentric strength of the hamstring muscles was determined using the Nordic exercise on a Norbord device prior to a 90 minute soccer match and after its end. Results. There was a significant decrease in eccentric strength at the end of the match (before the match: M = 306.91, SD = 59.26; after the match: Mean = 277.77 ± SD = 60.35 p =.000, Cohen’s d =.50). The imbalance in eccentric hamstring muscle strength between dominant and non-dominant limb before the match remained unchanged after its end. Conclusions. A professional football match significantly impacts on the ability of players to produce high speed eccentric strength in the hamstring muscle groups. Resistance to fatigue and eccentric strength, particularly at high speeds, are considerable factors in conditioning of professional soccer players. Eccentric muscle strength fatigue of the hamstring muscle group after a 90 min soccer match may provide a possible explanation for the greater risk of hamstring injuries under fatigue conditions. © 2021, CIC Edizioni Internazionali s.r.l..

- Description: Learning communities (LCs) in a variety of formats are touted as an effective strategy for continuing professional development (CPD) in physical education. This study’s purpose was to provide an overview of the research on LCs in physical education for professional development between 1990 and 2020. A scoping review undergirded the research process and search parameters included full-text empirical studies in 12 languages. Ultimately 95 studies were found. A descriptive analysis revealed teachers as the focus in 75% of the studies fewer studies focused on initial teacher education students, teacher educators, and facilitators. The largely qualitative studies reflected an international database (18 countries four multinational studies) with South Korea, the US, and England dominating the literature. Four features spotlight thematic findings: (a) facilitation, (b) the process of community development, (c) the focus of the group and (d) the product(s) of the group. Learning communities as a CPD approach in physical education appear to be effective in a variety of ways. Little evidence, however, exists regarding their sustained nature over time, or how teacher engagement in LCs may result in substantive student learning. Contributing to the scattered nature of literature to date was the interchangeable use of communities of practice (CoP) and other forms of LCs. Often communities were not theoretically aligned, the development process of communities not explained, nor evidence provided as to how the community studied contained the qualifying features of a CoP or LCs. Future research, therefore, should detail the nature of community and fidelity to the theoretical framework.

- Description: Objectives: Better understanding of compulsive exercise is needed in sports medicine. Whilst compulsive exercise may impact mental health, the limited research exploring the relationship between compulsive exercise and psychosocial outcomes is equivocal. The majority of studies have examined eating disorder populations where the eating disorder pathology might account for distress. This study explores relationships between compulsive exercise and mental health. Design: Cross-sectional observational study. Methods: Australian recreational exercisers and athletes (N = 1157; Mage 36.4, standard deviation = 12.9, 77 % female) recruited through sporting organisations, clubs, and gyms, completed measures of compulsive exercise, depression, anxiety, stress, life satisfaction, social physique anxiety, and self-esteem. Regression analyses examined relationships between dimensions of compulsive exercise and wellbeing. Results: After adjustment for eating disorder symptoms and sporting level, compulsive exercise was associated with increased risk of clinically-significant anxiety, depression, and stress symptoms. Compulsive exercise was also associated with lower life satisfaction and self-esteem, and higher social physique anxiety. Notably, different dimensions of compulsive exercise had varying relationships with outcomes, and avoidance and rule-driven behaviour and lack of exercise enjoyment were associated with poorer mental health and wellbeing. Conclusions: Results suggest that compulsive exercise is uniquely associated with a range of psychosocial and mental health outcomes. Results support the need to improve identification and treatment of compulsive exercise in sport and exercise settings. Results highlight that mental health intervention is an important component of treatment, and treatments targeting symptoms related to avoidance and rule-driven behaviour, and anhedonia may be valuable treatment components for those with compulsive exercise. © 2023 The Author(s)

The aim of this study is to explore what affects the acceptability of exercise interventions to better meet the needs of people with dementia and their carers as a dyad. Observations, field notes containing participant's and instructor's feedback, and focus groups with 10 dyads involved in Tai Chi classes for 3 or 4 weeks in two sites in the South of England were thematically analyzed to understand their experiences. Findings suggest that dyads' determination to achieve the benefits of Tai Chi facilitated their adherence, whereas a member of the dyad's low sense of efficacy performing the movements during classes was a barrier. Simplifying class content and enhancing the clarity of instructions for home-based practice will be key to support the design of future exercise interventions. © 2019 The Authors.
